Cov hmoov hlau 3D luam ntawv thev naus laus zisCov txheej txheem molding, cov ntaub ntawv kub, ua qhov tseem ceeb tshaj plaws ntawm cov khoom hlau 3D luam ntawv kev lag luam saw, kuj yog qhov muaj nqis tshaj plaws. Ntawm lub rooj sib tham kev lag luam luam ntawv 3D thoob ntiaj teb xyoo 2013, cov kws tshaj lij hauv kev lag luam luam ntawv 3D thoob ntiaj teb tau muab cov lus txhais meej ntawm 3d luam ntawv hmoov hlau, uas yog, qhov loj me tsawg dua 1 hli ntawm cov hlau me me. Nws suav nrog cov hlau ib leeg hmoov, alloy hmoov thiab qee cov refractory compound hmoov nrog cov khoom hlau. Tam sim no, 3D luam ntawv hmoov hlau cov ntaub ntawv suav nrog cobalt-chromium alloy, stainless hlau, hlau lag luam, tooj liab alloy, titanium alloy thiab nickel-aluminium alloy. Tab sis 3D luam ntawv hmoov hlau yuav tsum tsis yog tsuas yog muaj plasticity zoo, tab sis kuj ua tau raws li qhov yuav tsum tau ua ntawm qhov loj me me, qhov faib me me, sphericity siab, fluidity zoo thiab xoob ceev. Vim yog qhov sib txawv ntawm kev thov thiab cov txheej txheem molding tom qab, cov txheej txheem npaj ntawm cov hlau hmoov kuj txawv. Raws li cov txheej txheem npaj, nws feem ntau suav nrog cov txheej txheem tshuaj lom neeg lub cev thiab cov txheej txheem kho tshuab. Hauv kev lag luam hmoov metallurgy, cov txheej txheem xws li electrolysis, txo qis thiab atomization yog siv dav. Txawm li cas los xij, yuav tsum nco ntsoov tias ob txoj kev no muaj lawv cov kev txwv, tsis haum rau kev npaj hmoov hlau. Tam sim no, hmoov hlau rau kev tsim khoom ntxiv feem ntau yog ua los ntawm titanium alloy, alloy kub siab, cobalt-chromium alloy, hlau muaj zog thiab hlau tuag. Yuav kom ua tau raws li qhov xav tau ntawm cov khoom siv thiab cov txheej txheem tsim khoom ntxiv, cov hmoov hlau yuav tsum muaj cov yam ntxwv ntawm cov pa oxygen thiab nitrogen tsawg, qib spherical zoo, qhov faib me me ntawm cov khoom me me thiab qhov ceev xoob siab. Tam sim no, cov txheej txheem tseem ceeb ntawm kev npaj cov hmoov hlau rau kev tsim khoom ntxiv yog plasma rotating electrode (PREP), plasma atomization (PA), gas atomization (GA) thiab plasma spheroidization (PS), txhua tus tuaj yeem siv los npaj cov hmoov hlau spherical lossis ze-spherical.
